Single Layer PCB Vs Multi Layer PCB - Ubwino, Kuipa, Mapangidwe ndi Njira Yopangira.
M'mbuyomukupanga gulu losindikizidwa lozungulira, muyenera kusankha kugwiritsa ntchito PCB yakusanjikiza imodzi kapena mitundu ingapo. Mitundu yonse iwiriyi imagwiritsidwa ntchito pazida zambiri za tsiku ndi tsiku. Mtundu wa pulojekiti yomwe mukugwiritsira ntchito bolodi idzatsimikizira kuti ndi yabwino kwa inu. Ma board amitundu yambiri amakhala ofala kwambiri pazida zovuta, pomwe matabwa amtundu umodzi amatha kugwiritsidwa ntchito pazida zosavuta. Nkhaniyi ikuthandizani kumvetsetsa kusiyana kwake ndikusankha mtundu woyenera wa polojekiti yanu.
Kutengera mayina a ma PCB awa, mutha kuganiza kuti pali kusiyana kotani. Bolodi yokhala ndi gawo limodzi imakhala ndi gawo limodzi (lomwe limatchedwanso gawo lapansi), pomwe matabwa amitundu yambiri amakhala ndi zigawo zingapo. Mukawapenda bwino, muwona kusiyana kwakukulu momwe matabwawa amapangidwira ndikugwira ntchito.
Ngati mukufuna kuwerenga zambiri za mitundu iwiriyi ya PCB, pitilizani kuwerenga!
Kodi Single Layer PCB ndi chiyani?
Ma board a mbali imodzi amadziwikanso kuti matabwa a mbali imodzi. Ali ndi zigawo mbali imodzi ndi chitsanzo cha conductor mbali inayo. Ma board awa amakhala ndi gawo limodzi la zinthu zoyendetsera (nthawi zambiri zamkuwa). Bolodi lagawo limodzi limakhala ndi gawo lapansi, zigawo zachitsulo zoyendetsa, zotchingira zotchingira zoteteza, ndi chophimba cha silika. Mapulani amtundu umodzi amapezeka muzipangizo zambiri zosavuta zamagetsi.
Ubwino wa Single Layer PCB
